Somebody

Years after building a unique AI chatbot, Kim Sum uses the technology to create Somebody, a dating app built to connect — and linked to multiple crimes.

After Yeong Gi-eun experiences a nightmarish Somebody date, she and Lim Mok-won reach out to Sum to ask her for help in finding the man responsible.

Sum and Yun-o take their relationship to the next level. Meanwhile, Gi-eun goes to the CEO of Spectrum to ask for access to her personal chat history.

Mok-won and Gi-eun need to blow off some steam, so they take Sum along to a night club. Later, Mok-won tries to get Sum to face the truth about Yun-o.
